Compensation Public UI small issues

[damienen]

• [x] Needs a loading animation until compensations are fetched
• [ ] Calls to the API need to be made more efficient (in CompensationCards, the dataNftsInScT object contructs the NFTs before knowing if it needs them or not. It should first check what NFTs it needs and then construct them)
• [x] If an address is blacklisted from said compensation and they deposit their NFT as proof, they are shown like they will receive compensation, but they actually only receive their NFT back. This should be reflected in the UI
• [ ] If an address is blacklisted, on UI level the compensation amount is wrongly calculted

Good enough implementation for now. The other we will defer
